[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transformer carry-in device suitable for carrying a transformer into an electric room such as a building.

[0002]

2. Description of the Related Art Conventionally, as a transformer installed in an electric room such as a building, a molded transformer or a silicone dry type transformer, which is characterized by flame resistance, has been widely used. When these existing transformers are replaced with new transformers due to increase in capacity or progress of deterioration, there are various restrictions on the introduction of the new transformers.

That is, generally, an electric room of a building or the like is often provided underground, and the electric room is carried in from a passage for humans or a passage for vehicles. In this case, there is a particular limitation in height and width. On the other hand, the general method of carrying in a transformer currently implemented is as follows: (1) As shown in FIG. 5 and FIG.
It is loaded on the moving jig 3 having the above and moved and carried in.

(2) The transformer is divided into an iron core and a coil and carried in. At the destination, as shown in FIG. 7, the coil 4 is lifted by a crane 5 and assembled to the iron core 6 to assemble. .

[0005]

Among the above-mentioned conventional carrying-in methods, the former is restricted by the height dimension. On the other hand, in the latter case, the height and width are not restricted, but the cost required for reassembly after carrying in is large and the construction period is long. Further, in this case, when the coil 4 is inserted into the iron core 6, the height of the transformer needs to be about twice as high as that of the completed transformer, and the height of the ceiling is considerably required.

The present invention has been made in view of the above circumstances, and therefore an object thereof is that it can be carried in without being restricted by height and width dimensions, and can be installed locally at the destination. (EN) Provided is a transformer carry-in device which can be easily and without requiring a high ceiling height.

[0007]

In order to achieve the above object, the transformer carrying-in device of the present invention comprises a supporting jig for supporting the transformer in an already assembled state, and the supporting jig is used for carrying a carrier. A tool is used to support one end of the jig so that it can be undulated, and an expansion / contraction device is provided between the two jigs to elevate and lower the supporting jig by the expansion / contraction of the jig to change its inclination angle. Characterize. In this case, it is more preferable to provide the fulcrum portion at one end of the support jig so as to be movable in a direction of coming into contact with and separating from the expandable device.

[0008]

According to the above means, the transformer is set in the preassembled state on the support jig, and the expansion / contraction device is extended / contracted to raise / lower the support jig, and the inclination angle thereof is changed to carry in the transformer. Height and width can be changed. Therefore, it is possible to clear the dimensional restrictions in the carry-in passage and carry it in as desired.

In addition, in the installation place, by setting the expansion device to the maximum extension state, the transformer can be made close to the upright state. Therefore, the transformer is lifted from this state, and the carry-in device is pulled out to transform the transformer. By lowering the vessel, you can easily
Moreover, it can be installed without requiring a particularly high ceiling height.

In the case where the fulcrum portion at one end of the supporting jig is provided so as to be movable toward and away from the expansion / contraction device, the movement of the fulcrum and the expansion / contraction of the jack are performed together to tilt the supporting jig. The corners can be changed more, and thus the carry-in height and width dimensions of the transformer can be changed more.

Set to 6 to support. This supporting jig 16 is in a U shape in detail, and when tilted as shown in the drawing,
The transformer 15 is supported by the respective end surfaces of the iron core fastening fittings 13 and 14 and the outer peripheral surface of the coil 12 so as not to give deformation or characteristic distortion to the iron core 11 or the coil 12 of the transformer 15.

On the other hand, the carrying jig 17 is in the form of a flat plate, and has wheels 18 for carrying on the lower surface thereof, and a support plate 19 on one side of the upper surface thereof. A corner of one end of the support jig 16 is attached to the shaft 20 so as to be vertically rotatable, and thus the support jig 16 is supported so as to be capable of undulating with one end thereof as a fulcrum.

On the other side of the upper surface of the carrying jig 17, a telescopic device, for example, a jack 21 is provided, and the tip of the device is provided on the rear side of the central portion of the supporting jig 16. 22 is rotatably attached to a shaft 23 by means of a shaft 23 so that the jack 2 is provided between the carrying jig 17 and the supporting jig 16.
1 is provided so that it can expand and contract. It should be noted that this jack 21 can be operated by hydraulic pressure or the like, and has a mechanism having an extension / contraction length of two steps or more. By doing so, the range of adjustment of the expansion / contraction length can be increased, and by extension, the support jig 16
The adjustment range of the tilt angle as described below can be increased.

Therefore, in the case of the above configuration, the transformer 1

When 1 is expanded or contracted, the support jig 16 is undulated, and the carry-in height dimension and width dimension of the transformer 15 can be changed by changing the inclination angle thereof. Therefore, it is possible to clear the size restrictions in the carry-in passage and carry it in as desired.

In addition, in the installation place of the carry-in destination, by making the jack 21 fully extended, the transformer 15 can be made close to the upright state, so that the transformer 15 is lifted from this state and the carry-in device is installed. By withdrawing and lowering the transformer 15, it can be installed easily and without requiring the ceiling height to be as high as when inserting a coil into a conventional iron core.

In contrast to the above, FIGS. 3 and 4 show different embodiments of the present invention, in which a movable jig 32 having wheels 31 instead of the above-mentioned supporting plate 19 is provided in the carrying jig 17.
Is provided so as to be movable in a direction in which it comes into contact with and separates from the jack 21 by the wheel 31 (see the arrow in FIG. 3), and a corner of one end of the support jig 16 can be vertically rotated by the shaft 20 on the movable support 32. The supporting jig 16 is supported by one end of the supporting jig 16 so as to be able to rise and fall, and the supporting point is provided so as to be movable in a direction in which the supporting jig 16 comes in contact with and separates from the jack 21.

By doing so, the supporting jig 16
